Abstract

EL SISTEMA PROTECTOR EN FORMA DE UNA CONTROLADOR DE LA PRESION DE LA CIRCULACION DE LIQUIDO DE UN APARATO MEDICINAL PUEDE SER INEFICAZ A TRAVES DE LA IRRIGACION CON EL FLUIDO. PARA PODER IDENTIFICAR ESTE ERROR SEGUN EL INVENTO SE ANALIZA EN EL SISTEMA PROTECTOR LA PRESION ESTATICA Y LAS FLUCTUACIONES DE PRESION PRESENTES EN LA CIRCULACION. MEDIANTE EL REGISTRO DE DESPLAZAMIENTO DE FASES DE LAS SEÑALES DE FLUCTUACION DE PRESION EN LUGARES DIFERENTES DE LA CIRCULACION SE PUEDE CONCOER LA INTERRUPCION DE LA CIRCULACION.THE PROTECTIVE SYSTEM IN THE FORM OF A LIQUID CIRCULATION PRESSURE CONTROLLER OF A MEDICINAL DEVICE MAY BE INEFFECTIVE THROUGH IRRIGATION WITH THE FLUID. IN ORDER TO IDENTIFY THIS ERROR ACCORDING TO THE INVENTION, THE STATIC PRESSURE AND THE PRESSURE FLUCTUATIONS PRESENT IN THE CIRCULATION ARE ANALYZED IN THE PROTECTIVE SYSTEM. THROUGH THE RECORD OF MOVEMENT OF PHASES OF THE SIGNALS OF PRESSURE FLUCTUATION IN PLACES DIFFERENT FROM THE CIRCULATION, THE INTERRUPTION OF THE CIRCULATION CAN BE KNOWN.
